Both these methylation reactions are vital for growth and cell reproduction.[9][10] Methionine, a sulfur-containing, essential amino acid, is a precursor of S-adenosylmethionine, a cofactor for one-carbon metabolism and the final methyl donor for the methylation of DNA, RNA, proteins, and phospholipids.[11] The methionine synthase plays a paramount role in the synthesis of nitrogenous bases (purines and pyrimidines) involved in the formation of DNA
During the lyophilization (freeze-drying) process, the peptide often forms a solid, compacted puck or disc at the bottom of the vial
